A 15-month project to restore the historic site concluded just in time to welcome back the public with a flag-raising ceremony. Main contractor UPM Tilhill worked closely with lead design consultant Scott Wilson to carry out the work on the 190ha site.
The work was funded by a £1.9m Heritage Lottery Fund grant and has helped to restore much of the vision of Capability Brown, who redesigned parts of the park in the 1760s. It included a complete restoration of the historic Temple Gardens and major works on the lake.
The park, used as a training ground for the Polish army during the Second World War, presented unique challenges. Scott Wilson project manager Jon Rooney said: "We dealt with a large quantity of Second World War unexploded ordnance in the lake during the de-silting process and this had to be removed and safely destroyed before work could progress.
"This challenging restoration project has brought Langley Park back to life, restoring features and views and improving access to its hidden treasures."
Scott Wilson has been involved since 2006. A visitor centre designed by Cotterell, Thomas and Thomas was also installed.
